Product description

Product Description

E3 has taken the best features from traditional spark plugs, such as cut-back ground electrodes and surface gaps, and combined them to create a new ground electrode design. Surface gap plugs present the flame kernel to the piston (or rotor) more directly, reducing the travel time from the spark to the combustion gases (although this difference is only measurable in hundred-thousands of a second, at 5000 RPM, they can add up). This avoids the "doughnut" shaped flame front created by standard spark plug electrodes. This is achieved in the E3 design through the open section at the top of the ground electrode. E3 spark plugs combine the benefits of additional sharp electrode edges with a cut-back electrode design used on some racing spark plugs. The increase of available edge-to-edge surface area encourages a more rapid spark discharge while also reducing quenching and shadowing. The two legs that support the special geometry of E3's powersports plug ground electrode aid in heat dissipation for longer electrode life. The center electrode on E3 spark plugs is created from nickel alloy with a copper center core for both improved conductivity as well as heat dissipation.

E3 Power Sports spark plugs are a clear breakthrough in spark plug technology. Developed by researchers from leading engineering universities, E3's patented electrode design allows for a better spark, and resulting more complete flame kernal and flame front extending off the electrode, producing better overall localized pressure inside your boat, jetski, ATV or snowmobile's engine's cylinder(s). This in turn leads to the fuel/air mixture injected into the cylinder being more cleanly consumed, lessening the level of greenhouse gases emitted, increasing energy efficiency and generating more horsepower.

Why You Need E3 Spark Plugs
As the designated catalyst for the ignition of fuel in gasoline power sport vehicle engines, spark plugs are a small, but constant factor in the workings of the vast majority of snowmobiles, ATVs, jetskis, boats and vehicles with similar performance needs. What owners of these vehicles may not realize is that their choice of spark plug could play a significant role in reducing the level of greenhouse gases that their engines give off, as well as increasing their overall fuel economy and potential power output. This is where E3 Spark Plug's DiamondFire technology comes in.

DiamondFire Technology
For the last 100 years, the only real advance in consumer spark plug technology has been to develop ways to make them cheaper. E3 Spark Plug's DiamondFire technology changes all of that through an improved electrode design that provides for more efficient burning of your engine's air/fuel vapor, leading to more pressure in the cylinder. These improvements are measurable, confirmed and based on the following design elements found in existing performance spark plugs.

First, the DiamondFire electrode directs the flame kernel to the piston more directly, reducing the travel time from the spark zone to the end gases via the open section at the top of the electrode. Given the short time available to get combustion started, the faster you can get the flame to the piston, the better. Second, the physical features of the electrode project further forward into the combustion chamber. This brings the spark zone closer to areas of probable "good" air/fuel mixture and also creates beneficial "micro-aerodynamics" within the spark zone. The initial combustion wave leaves the spark area at supersonic speeds above Mach 1, and the elevated edge provides a kind of chimney effect so the next round of air/fuel mixture gets into the spark zone more easily. Finally, the E3 electrode design features forced edge-to-edge spark discharge, which is the best way to get a spark to leave a surface. This improves upon the phenomena that drove race car drivers to "cut back" ordinary electrode spark plugs in order to improve the spark discharge. The spark itself occurs only when an avalanche of electrons migrates from the two electrodes (anode to cathode). Sharp edges are better at initiating electron migrations, and these accelerated electrons collide with matter inside the spark zone to release additional electrons. This design ensures that the whole population of electrons works to create a plasma channel through which the spark current flows more easily, resulting in an increase in both power output and fuel economy, while reducing emissions in gasoline engines and the build up of carbon deposits on engine surfaces.

Key Features:

  • DiamondFire electrode technology that creates a superior spark and resulting flame front extending further into the cylinder, producing more localized pressure.
  • Power increased > 6% to 12% (depending on engine class).
  • Fuel efficiency improved > 4% to 13% (depending on engine class).
  • Emissions reduced in 2 and 4-stroke engines (after 50 hours).
    • 58% CO emissions reduction.
    • 42% hydrocarbon reduction.
  • Quicker starts and near elimination of performance inhibiting carbon deposits.
  • Dramatically longer plug life.
  • Limited lifetime warranty.
